As the New York Times reports on Iowa's same-sex marriage case argued on December 9:

The legal core of the case, Varnum v. Brien, is whether the state’s
10-year-old law defining a “valid” marriage as only “between a male and
female” violates the Iowa Constitution’s guarantees of equal treatment
and due process.

A trial court judge ruled last year that the law
was unconstitutional and that a dozen gay men and lesbians had been
wrongly denied marriage licenses in Polk County, which includes the
state capital, Des Moines. The state appealed the ruling, leading to
Tuesday’s oral arguments.

But the technical details of the law
and the Constitution were only part of a free-wheeling discussion
lasting nearly two hours in which the seven justices repeatedly
interrupted the lawyers, demanding that they parse and defend their
positions.

The Iowa court has posted a video stream on the oral argument, but for the moment it doesn't seem to be working, check here: www.judicial.state.ia.us.

As the New Jersey Star-Ledger reports, the NJ Civil Union Review Commission's final report will conclude that the "state's civil
unions law fails to adequately protect same-sex couples" and same-sex marriage should be allowed.

The Civil Union Review Commission report is not available yet, but an interim report and many other materials are available on the Commission's website here.

And in CALIFORNIA

as well as nationwide, protests over Proposition 8 continue. Today's action, as discussed in the LA Times here and elsewhere is a work stoppage:"Gay rights activists are encouraging people to “call in gay” to work
today to demonstrate how integral gay people are to American society."
